Ratchet basket press

In France in 1925, the horizontal rotating plate press was introduced by Joseph Vaslin. By turning the basket press on its side, making it rotatable, and incorporating in-situ chains, the press cake could be crumbled automatically. This was a major advantage over vertical basket presses that required considerable manual labour for crumbling and emptying. This press was only mass produced after Gaston Bernier, head of Constructions Méca-Métalliques Chalonnaises (now Bucher-Vaslin) purchased the process in 1945.
